ACETYLENE-GENEBATOR.

Specification of Letters Patent.

Patented J une 3, 1919.

Application filed June 27, 1917. Serial No. 177,262.

T 0 all whom it may concern Be it known that we, CLAUD J. CLEr'roN andJ. CLnrToN, citizens of the United States, residents of Owatonna, countyof Steele, State of Minnesota, have invented centain new and usefulImprovements in Acetylene-Generators, of which the following is a secification.

' The object of our invention is to 'provide improved means for mountingan auxiliary carbid hopper in the gas bell to the end that it may beconveniently removed for refilling when desired and air excluded fromthe generator during the operation.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly polnted outin the claims.

In the accompanying drawings forming part of this specification,

The figure is a vertical sectional view through a generator embodyingour invention.

In the drawing, 2 represents the generating tank, having a water chamber3 within which a sleeve 4 is arranged, supporting a carbid hopper 5. 6is the gas bell having its lower end immersed in the liquid seal withinthe annular chamber 7 8 is a water supply pipe through which fresh wateris introduced to the tank, 9 is a pipe wherein the operating rod 10 forthe agitating device 11 is mounted. 12 is a pipe containing a similarrod connected with the agitating device 13, the upper part of the pipe12 having means for connecting a pump thereto for withdrawing the waterand sludge from the bottom of the tank. 14 is a gas service pipe,

connected with a pipe 15 located within the tank and having a filter 16within the gas bell, through which the gas flows to the service pipe.

The generator has the usual cover 17 and a space 18 beneath the coverand above the bell which permits the rise and fall of the bell in theoperation of the machine. 19 is the top of the carbid hopper, having anopening, 20 therein, and 21 is a sleeve mounted on said cover andencircling said opening A second sleeve 22 is carried by the gas belland telescopes with the sleeve 21. The sleeve 22 has the function ofdirecting-any moisture which may collect thereon down past the upper endof the sleeve 21 and prevent it from entering the carbidihopper.

The atxiiliary carbid ho per has" a jacket- 23' the jacket 23- extendsbelow the top ofthe sleeve 21 and prevents any possibility of carbidlodging on the top-of the sleeve 21 or between it and the sleeve 22, allthese details 10f construction contributing to a more perfect operatlonof the machine and eliminat- 7 ing the danger which might result fromspilling of the carbid around the top of the hopper. The hopper 25 has adouble coneshaped lower end 26 and a valve 27 is provided for closingthe opening and has a stem 28 which projects through the c'over'29 forsaid hopper and has a threaded end and a stuffing box 30 therein forpreventing any escape of gas. The cover 29 is arranged to bear on thejacket 23 and a yoke 31 has a hook atone 'end for engaging a lug 32 onsaid jacket and a thumb screw 33 at its opposite end that is tapped intoa lug 34 on the other side of said jacket. The middle portion of thisyoke bears at 35 on the center of the cover and when the thumb screw istightened, the cover will besqueezed down to clamp it on the jacket andprevent the entrance of air and escape of gas through the top of theauxiliary carbid hopper. To remove this hopper, it is only necessary totake oii the cover 17 and lift the jacket and hopper out of the bell,when thehopper may be refilled and replaced in the bell, ready todischarge its contents into the main hopper beneath in case the supplyof gas is low ,ata time, such as in the evening, when it is not:(spvenient to empty the generator and re- In various ways the detailsof construction herein shown and described may be modified and still bewithin the scope of our invention.

We claim as our invention:

1. An acetylene gas generator comprising a tank adapted to contain asupply of water, a carbid hopper therein, a gas bell encircling saidhopper, the top of said hopper and said bell having oppositely arrangedopenings therein, sleeves mounted on said hopper and said bellrespectively and encircling said openings and arranged to telescope withthe rise and fall of the gas bell, said hopper sleeve being seatedagainst the top of the bell and said bell leeve being seated against thetop or the hopper when the bell is in its lowered position, therebysealing the bell against the escape of gas or the entrance of airtherein.

2. An acetylene generator comprising a tank, a carbid hopper therein, agas bellencircling said hopper, the top of said hopper and said bellhaving openings oppositely arranged therein, sleeves mountedrespectively on said bell and said hopper in telescoping relation, andan auxiliary carbid hopper removably fitting Within the opening in saidbell and Within said sleeves.

3. An acetylene gas generator comprising a tank, a carbid hoppertherein, a gas bell, said'hopper and said bell having oppositelyarranged openings, telescoping sleeves encircling said openings and anauxiliary carbid hopper removably mounted in the opening in said gasbell and depending Within said sleeves and having a discharge openingand valve therefor accessible through the top of said tank.

4. An acetylene gas generator comprising a tank, a carbid hoppertherein, a gas bell, said hopper and said bell having oppositelyarranged openings therein, a jacket fitting Within said opening andhaving a flange to bear on the Wall of said bell around the openingtherein, an auxiliary carbid hopper fitting Within said jacket, meansfor clamping said auxiliary hopper on said jacket, said auxiliary hopperdepending within said jacket and having a valve opening and a valveoperated through the top of said jacket and auxiliary hopper, saidjacket and said auxiliary hopper being removable from said bell forfilling said hopper at a point remote from said generator.

5. An acetylene gas generator comprising a tank, a carbid hopper thereinhaving a closed top provided with a filling opening, a gas bellencircling said hopper and also having an opening therein opposite theopening in said hopper, sleeves mounted resaid sleeves and having adischarge openmg and valve therefor.

(5. An a'cet lens as enerator com )llSlIW b t: O

a tank adapted to contain a supply of Water,

a carbid hopper therein having a closed top, a gas bell encircling saidhopper and having a liquid seal, said hopper and said bell havingoppositely arranged openings therein, an auxiliary carbid hopper fittingWithin said openings and having means for discharging the carbidtherefrom into the'hopper of said generator, said auxiliary hopper beingremovable from said bell for filling it at a point remote 'fromthegenerator, and means encircling'the openings in said bell and generatorhopper for sealing said hopper and said bell against the entrance of airand the escape ofgas When said auxiliary hopper is removed.

7. An acetylene gas generator comprising a tank adapted'to contain asupply of Water, a carbid hopper therein having a closedtop, a gas bellencircling said hopper and having a liquid seal, said hopper andsaid'bell having oppositely arranged openings therein,an auxiliarycarbid hopper fitting Within said openings and having means fordischarging the carbid'therefrom into the hop per of saidigenerator,saidauxiliary hopper being removable from said bell for filling it ata.point remote fromthe generator, and telescoping sleeves encircling theopenings in said bell and generator hopper for sealing said hopper andsaid bell against the entrance of air and the escape of gas When saidauxiliary hopperis removed.

In Witness \vhereof We have hereunto set our handsthis 18 day of June1917.
